Microscope
A telescope uses lens and mirrors to collect and focus light from distant object.
the reflecting telescope uses mirrors and lenses. The refracting telescope does not include the mirrors.
Optical!!
Newtonian telescope
Reflecting TelescopeA reflecting telescope uses a lens and two mirrors. The lens is positioned at the eyepiece, and thus the focus, which the two mirrors generated by specifically redirected light. There are two types of reflecting telescopes with one lens and two mirrors, the Newtonian Focus and the Cassegrain Focus.
refractor
Concave mirrors are commonly used in devices such as makeup mirrors, satellite dishes, and reflecting telescopes to focus light and create magnified or clearer images.
A reflecting telescope.
A reflecting telescope forms an image by using a combination of curved mirrors to focus light. It was invented as an alternative to the refracting telescope.
A Telescope uses lenses or mirrors to collect and focus light from distant objects. With the advancement in optical research we are capable to watch the stars and planets better than before. Our information about universe largely depend on telescopes.
The Hubble Telescope uses both mirrors and lenses to focus on images.
Concave mirrors are used in reflecting telescopes, makeup mirrors, and headlights to focus light rays. Convex mirrors are used in security mirrors, wide-angle rearview mirrors in cars, and magnifying glasses to provide a wider field of view or to reduce image distortion.
